Gathering furnace and regenerator parameters
Like any other manufacturing process, a good understanding of your furnace and regenerator operating conditions is key to determining the best checkerwork to meet your expectations in terms of lifetime, maintenance, energy savings and CO2 emissions.
From a set of parameters defined by the glassmaker or the furnace engineering company (chamber dimensions, fuel consumption, temperatures of fumes entering the regenerator, cullet ratio, etc.), SEFPRO can carry out numerical simulations to predict regenerator efficiency with different CRUCIFORMS® checkerpacks and compare them to other regenerator technologies.
Also, at the design stage of new furnaces, these simulations can support the optimization of regenerator size to achieve the best trade-off between its CAPEX and the furnace OPEX.

Customized solutions to meet your needs
Every thermal study investigates several solutions to support your design selection in consideration of economic and technical constraints and goals. Decision-making criteria can involve, for instance, the reduction of maintenance costs by minimizing channel plugging risk or the maximization of energy efficiency by enhancing heat exchange capability.
Our thermal study also provides you with an evaluation of all the critical parameters related to regenerator operation: furnace fuel consumption, velocities and temperatures of air and fumes along the checkerpack channels, heat exchange areas, weight of the checkerpacks, and finally the overall regenerator efficiency.
Based on the numerical results obtained, for each potential solution gas and CO2 savings can be estimated over the years as well as the initial investment for the checkerpack supply. This valuable information supports the analysis of the financial and environmental aspects of regenerator design and construction, and facilitates data-driven decision making when selecting the products to be used.
How accurate are the thermal study results?
REGEN, the code used in SEFPRO’s thermal studies, was developed in collaboration with renowned French research institutions and validated through extensive field tests at both pilot and industrial scales. Nowadays, several established engineering companies in the glass industry have recognized the value and accuracy of SEFPRO’s numerical model.
